TCDS E00094EN Page 3 of 6 NOTES NOTE 1. NOTE 2. NOTE 3. ENGINE RATINGS Engine ratings are based on calibrated test stand performance under the following conditions: 1. Sea level static, standard pressure (14.696 psia), up to the flat rating ambient temperature °F 2. No customer bleed or customer horsepower extraction 3. Ideal inlet, 100% ram recovery 4. Production aircraft flight cowling 5. Production instrumentation 6. Fuel lower heating value of 18,400 BTU/lb. TEMPERATURES The PW1217G is designed to be operated within the Normal Take-off (NTO) regime where the normal thrust of the propulsion system is within that defined for normal operation. In instances where higher thrust is necessary, such as one engine inoperative, an increased power setting is available which is referred to as the Maximum Takeoff Power Setting (MTO). Usage of the MTO setting will require additional action as outlined in the Airworthiness Limitations manual (P/N 5305822) and the Engine Maintenance Manual (P/N 5305824). Maximum permissible Indicated Turbine Temperatures (ITT) are as follows: Takeoff (5 minutes)* 1,102°C / 2,015°F Maximum Continuous 1,032°C / 1,890°F *The normal and maximum 5 minute takeoff rating may be extended to 10 minutes for engine out contingency. Indicated Turbine Temperatures (ITT) at start-up 1,078°C / 1,973°F Oil outlet temperature: Continuous operation: 168°C / 335°F. Maximum oil temperature 177°C / 350°F for up to 20 minutes. Total operation between 168°C / 335°F and 177°C / 350°F cannot exceed 20 minutes. See Installation and Operating Manual, PWA-8503 for details. Minimum oil temperature at idle, before takeoff power operation: 49°C / 120°F Minimum oil temperature for ground operation: -40 °F / -40 °C Fuel Temperatures: See Installation and Operating Manual, PWA-8503 (All Models) Component Temperatures: See Installation and Operating Manual, PWA-8503 (All Models) PRESSURES Fuel pressure limits: Fuel pressure at the engine fuel pump inlet during operation shall be maintained at not less than 5.0 psi above the true vapor pressure of the fuel but not greater than 100 psi above the absolute ambient pressure with a vapor/liquid ratio of zero. The maximum allowable pressure at the fuel pump inlet after shutdown is 121 psig. Oil pressure limits: Minimum: 50 psig at idle. Variable by N2 Speed off idle. See Installation and Operating Manual, PWA- 8503 Maximum: 175 psig Oil supply pressure is measured relative to main lube pressure. Temporary interruption associated with negative “g” operation is limited to 7 seconds maximum. Normal oil pressure will be restored rapidly once the negative “g” effect has been eliminated.
